Hi, can anyone advise whether LK8000 can merge traffic from multiple bluetooth sources? I know that XCSoar can.
Thank you, Guy

Hello, I mean that I would like to have two Lilygo T beam Supremes. One I would like to output Legacy data, the other P31 data. I have one already and it works perfectly with my phone. If I was to get another, could LK8000 accept to sources of data, combine, and display on one Flarm radar screen.
Thank you, Guy

Hi Bruno,

I have no Flarm Radar when running two Flarm sources.

I have two t-beams connected via Bluetooth to my android mobile running the latest version of LK8000. They are both transmitting $PFLAU sentences in Terminal as expected.
CHANNEL A is Disabled.
Channel B is Enabled receiving Legacy Flarm data. Status = GPSFix Flarm Baro
Channel C is Enabled receiving P31 Pilot Aware data. Status = GPSFix Baro
If either Channel B or C is Disabled, then the Flarm Radar multimap appears.
When Channel B and C are both Enabled, the Flarm Radar is inactivated.

Have a missed a setting somewhere?
Can I be certain that both Flarm sentences are being merged correctly?
Or is one Flarm channel being totally excluded.

I'm grateful for any advice.

Guy

I have an update. It would appear that having two GPS inputs, which will never be exactly the same, gives a conflict in LK8000. If i disable GNSS data in the soft RF settings then i get the Flarm Radar back.
